v2.02.137 SDLL137 — Structural modification of a beam

Summary

The purpose of this test case is to validate the procedure and the structural modification calculation based on the measured information.

The structural modification method used is based on the joint exploitation of measured data and the numerical model of the modification made to the initial structure. The substructuring technique is then used to couple the two models.

For this test case, the measurement was simulated numerically and the reference results are obtained by direct calculation on the complete structure.
